RX8010SJ clock module is suitable for intelligent sweeping robots

    In the navigation module, to achieve high altitude map restoration, it is necessary to ensure a wide range and high accuracy during map information collection. To achieve large-scale signal measurement, high-power laser diodes are required, ROHM's laser diode RLD90QZW5 has advantages such as a 25W power and converging light spot. When performing laser ranging, the emitted laser signal is transmitted further and the beam is more focused, resulting in a larger range of collected distance. To avoid the problem of insufficient accuracy in map information collection caused by inaccurate measurement of the single turn rotation time of the rotating motor, this solution uses KODENSHI's slot type photoelectric switch SIT210 to detect the marker position at the code wheel of the rotating motor through photoelectric signals, achieving accurate measurement of the single turn operation time of the rotating motor. The distance information corresponding to the angle is more accurate, and the highly restored cleaning map makes the navigation module's path planning more accurate and improves. The cleaning efficiency of intelligent sweeping robots.

To ensure high stability of distance information collection, a high stability reference frequency source is required. The RTC product RX8010SJ under Epson Crystal oscillator company has a built-in 32.768K crystal oscillator, which is calibrated before leaving the factory and has good stability, ensuring that the internal clock of the MCU is more stable and reliable.

The RX8010SJ imported crystal oscillator is very suitable for real-time clock modules, with the following characteristics: 1.5 ± 23ppm high precision, ensuring time readiness, improving product reliability, sensors applied outdoors in relatively harsh environments, the working temperature of RX8010SJ is -40~85 ℃, industrial grade can ensure that the system clock is not affected in outdoor environments, improve product experience and quality, RX8010SJ is powered by 3V and has a power consumption of only 160nA under normal operation. Ordinary CR2032 batteries generally have an energy density of 160mAh and can be used for more than 3 years when powered by button batteries, ensuring continuous operation throughout the product's life cycle and improving product stability. RX8010SJ is manufactured by EPSON. With guaranteed quality, it integrates a 32.768kHz crystal oscillator and can directly output as a low-speed system clock for MCU.
